41. :The solution with spherical trigonometry has problems when two of the points P, A, B are identical or antipodal . 42. E . g . if A and B are antipodal then sin P 1 / sin p 1 is 0 / 0. 43. Craven _ former teacher, classical music devotee, Guaspari enthusiast, artist in search of an antipodal project _ saw his destiny. 44. A general vector that points to any place on the surface is written as a antipodal ) pairs of the kets listed above. 45. Three "'antipodal cells "'form on the opposite ( chalazal ) end of the ovule and later degenerate. 46. Half of these antipodal pairs are in New Zealand and Spain / Morocco with A Coru�a, Spain as Christchurch's antipode. 47. At ten miles a day, you need 1250 days ( less than four years ) to traverse the distance between antipodal points. 48. When there is additional matter density, the solution can be thought of as an Einstein spherical universe with two antipodal black holes. 49. The full article can be downloaded free of charge here It is made clear that the mechanism for antipodal volcanism is not known. 50. O'Reilly's is an " Antipodal Shangri-la, " in the words of my friend, Aurelio.
